Kate Gosselin says she feels sad for her eight children, as the family prepares for the final episode of their TLC reality show "Kate Plus 8," and adds that she is sure viewers will see them on television in the future.

The series finale of the show, a spin-off of her original program "Jon & Kate Plus 8," is set to air on Monday, September 12 at 9 p.m. ET.

"But there's also fear, because this has been ... has been the start, essentially, of my career and my job and the way I've been providing for my kids for six years," she added. "I want the best for my kids. I think that to be a good parent is to work as hard as you can and give them the best opportunities in life and this has provided that."

The TLC series saw Gosselin, 36, living life as a single mother of sextuplets - 7-year-old Alexis, Hannah, Aaden, Collin, Leah and Joel, and twin daughters, Cara and Madelyn, who are 11. Gosselin reportedly earned $250,000 per episode, according to TVGuide.com. (Check out a list of the highest-paid stars on television)

"Jon & Kate Plus 8" debuted in 2007 following a series of specials and featured her and then-husband Jon. The series changed its name in 2009, when the couple divorced, and ratings have since declined.

When asked if she wanted to return to television, Gosselin said on the "Today" show: "I think at this point, the best opportunity for all of us would be me continuing in TV as a way to provide for my kids. I wouldn't be opposed to it. I'm sure you will see my kids again at some point."

TLC had announced on August 15 that "Kate Plus 8' would end on September 12 after 150 episodes, adding that the network "hopes to check in with Kate and the family periodically with specials in the future."

"We've had a great run!" Gosselin said on Twitter on Monday. "Six years of whirlwind funfilled adventures thanks to TLC and our many many supportive and diehard fans! While it is very sad for me and the kids (there were many tears at the breakfast table this morning!), we are looking forward with great anticipation to our bright future!"

Gosselin added that she hopes to have more time for "motivational speaking, book writing and other fun work opportunities."

"And maybe even some dating??!!" she added. "We wish our fans well. And remember, this is not 'goodbye'. I prefer to say 'See you around!' Xoxo."

Meanwhile, during his Ridiculist segment on his CNN show on Tuesday, Anderson Cooper sarcastically mocked Gosselin after playing a clip from "Kate Plus 8." In the clip, Gosselin becomes upset when the children's baby sitter, Ashley, let Gosselin's daughter, Maddy, give a slice of pizza to the family's body guard, Steve, with her bare hands.
